Benefits of technology

The thermal grill design effectively warms the entire wipe surface, offering a comforting feel by generating a pleasant warmth sensation across the skin, reducing discomfort and achieving the desired temperature change with minimal heating chemistry.

Problems solved by technology

In recent studies, it has been shown that baby wet wipes currently on the market are sometimes perceived to be uncomfortably cold upon application to the skin, particularly for newborns.
However, one drawback of utilizing these certain chemistries is the amount needed to warm the wipe.
However, there is a need to provide a thermal grill that does not provide a feeling of discomfort, but a pleasant feeling of warmth.

example 1

[0060]A multiple layer wipe having an area of approximately 290 centimeters2 was prepared comprising about 70% pulp fiber and 30% melt-blown fibers and an aqueous wet wipe solution was added to the sheet. A strip of plastic film was placed over the wipe and a warming lotion was applied to the wipe substrate with a roller creating a patterned thermal grill on the wipe. The warming lotion comprises a magnesium chlorides temperature change substance and mineral oil applied to the surface of the wipe. In this example, heat is generated when the water in the wipe combines with the magnesium chloride in the warming lotion.

[0061]Approximately 1.2 grams of the warming lotion was applied to the wipe substrate covering approximately 35% of the wipe. Therefore, approximately 9.5 mg / centimeters2 of the warming lotion was added to the wipe. Images were taken utilizing an infrared camera and illustrated localized maximum temperatures of between 39 and 49° C. There was little heat distribution awa...

In this example, heat is generated when the water in the wipe combines with the magnesium chloride in the warming lotion.

[0063]Approximately 2.4 grams of the warming lotion was applied to approximately 35% of the wipe. Therefore, approximately 18 mg / centimeters2 of the warming lotion was added to the wipe.

Abstract

Generally stated, the present disclosure relates to wiping substrates such as wet wipes and dry wipes that include a thermal grill utilized to deliver a warming sensation. In an exemplary aspect, disposed on at least one structural layer of the wipe substrate is a thermal grill. The thermal grill includes an alternating pattern of thermally active areas and secondary areas that provide a feeling of warmth to a user of the wipe across the entire surface of the wipe. The thermally active portions of the wipe include a temperature change substance that when in liquid communication with an activation agent is adapted to provide a temperature change of at least 5° C. from the temperature of the secondary portion. By providing a thermal grill with thermally active portions, the entire wipe gives the user of the wipe a warming sensation.

Description

FIELD[0001]The present disclosure generally relates to wipes that are self-warming or become warm quickly after dispensing. More particularly, wipes having alternating patterned thermally active areas that provide a warming sensation for the entire wipe is disclosed.BACKGROUND[0002]Wet wipes and dry wipes and related products have been commonly used by consumers for various cleaning and wiping tasks. For example, many parents have utilized wet wipes to clean the skin of infants and toddlers before and after urination and / or defecation. Many types of wipes both wet and dry are currently commercially available for this purpose.[0003]Today, many consumers are demanding that personal health care products, such as wet wipes, have the ability to not only provide their intended cleaning function, but also to deliver a comfort benefit to the user. In recent studies, it has been shown that baby wet wipes currently on the market are sometimes perceived to be uncomfortably cold upon applicatio...
